Visually check the quality of the components. If something of the delivery is not as expected please immediately contact VAT.Notice:Please do not throw away the original packaging. It might be useful in a case of service to return the components to VAT2.2 Installation into the systemThe valve seat side is indicated by the symbol "" on the connection flange.1. Clean the sealing surface and the O-ring seal of the mating flange.2. Move the pendulum valve in the correct mounting position with the crane. ATTENTION: Do not hit the sealingsurfaces during manipulation!3. Set 2 screws in one line4. Set two additional two screws 90° to the line which is build by the first two screws.5.

Cycling the valve at these temperatures may reduce the cycle life of the mechanism. See “1.1 Technical data”.4 Trouble shootingIf you need any further information, please contact one of our service centers. You can find the addresses on our website: http://www.vat.ch5 Maintenance & repairsUnder clean operating conditions, the valve does not require any maintenance during the specified cycle life. Contamination from the process may influence the function and requires more frequent maintenance.Before carrying out any maintenance or repairs, please contact VAT. It has to be individually decided whether the maintenance/repair can be performed by the customer or has to be carried out by VAT. The fabrication number on the valvehas always to be specified.All supplies (e. g. compressed air, electrical power) must be disconnected for removal/installation of the valve from/into the system and for maintenance work.Even with disconnected supply, loaded springs and/or air cushions in cylinders can be potential hazards.Keep fingers and objects away from the valve opening!Products returned to VAT must be free of harmful substances such as e.g. toxical, caustic or microbiological ones. If products are radioactively contaminated, fill in the VAT form «Contamination and Radiation Report» and send it with the product. The form is available at VAT. The maximum values indicated in the form must not be exceeded.5.1 Cleaning of the sealing surfacePlease wear safety glasses if you start with any maintenance work on the valve.5.2 Exchange of gate o-ring and glidersRemove the gate gliders from the valve gate with a little tool e.g.VAT recommends that whenever the gate o-ring is changed to also change5.3 Exchange of bellows feedthrough unitBefore mounting the new bellows feedthrough be aware about the flatencoding sections on the actuator shaft. This flat encoding sectionshould orientate the valve gate later on.6 Drawing7 Spare partsPlease specify the fabrication number of the valve (see yellow label on valve) when ordering spare parts. This is to ensure that the appropriate spare parts are supplied.8 WarrantyEach product sold by VAT Vakuumventile AG (VAT) is warranted to be free from the manufacturing defects that adversely affect the normal functioning thereof during the warranty period stated in VAT's «Terms of Sale» immediately following delivery thereof by VAT, provided that the same is properly operated under conditions of normal use and that regular, periodic maintenance and service is performed or replacements made, in accordance with the instructions provided by VAT.

气动锁止阀工作原理
气动锁止阀工作原理English:The working principle of a pneumatic lock-up valve is based on the use of pneumatic pressure to control the opening and closing of the valve. When there is no pneumatic pressure applied, the valve remains closed, preventing the flow of fluid through the system. When pneumatic pressure is applied, it activates the mechanism inside the valve, allowing it to open and let the fluid flow. The pneumatic pressure is used to lock the valve in the open position, ensuring a continuous flow of fluid until the pressure is released, and the valve returns to its closed position. This type of valve is commonly used in applications where it is essential to control the flow of fluid and maintain a secure and stable position of the valve during operation.中文翻译:气动锁止阀的工作原理是基于利用气动压力来控制阀门的开启和关闭。
当没有施加气动压力时，阀门保持关闭状态，防止流体通过系统。

气锁阀原理
气锁阀原理气锁阀是一种常用的流体控制装置，它具有独特的工作原理和广泛的应用范围。
气锁阀的原理主要是利用气体的密度和流动特性来实现流体的控制和密封。
在工业生产中，气锁阀被广泛应用于粉状物料的输送、气固两相流的控制以及防止气体泄漏等方面。
下面我们将详细介绍气锁阀的原理及其工作过程。
气锁阀的原理主要包括气体密度、气体流动和密封性能。
首先，气锁阀通过控制气体的密度来实现对流体的控制。
当气锁阀处于关闭状态时，气体在阀门内部被压缩，形成高密度的气体层，从而有效地阻止了流体的泄漏。
当气锁阀处于开启状态时，气体被释放，流体得以自由流动。
其次，气锁阀利用气体的流动特性来实现流体的控制。
通过控制气体的流动速度和方向，气锁阀可以有效地控制流体的输送和停止。
最后，气锁阀具有良好的密封性能，能够有效地防止气体泄漏，保证系统的安全运行。
气锁阀的工作过程主要包括密封、充气、排气和流动。
在密封阶段，气锁阀处于关闭状态，气体被压缩形成高密度气体层，有效地阻止了流体的泄漏。
在充气阶段，气锁阀释放压缩气体，使流体得以自由流动。
在排气阶段，气锁阀再次关闭，排出残余气体，为下一轮的工作做准备。
在流动阶段，气锁阀控制气体的流动速度和方向，实现对流体的精准控制。
总的来说，气锁阀通过控制气体的密度、流动和密封性能，实现了对流体的精准控制和密封。
在工业生产中，气锁阀被广泛应用于粉状物料的输送、气固两相流的控制以及防止气体泄漏等方面。
它具有结构简单、操作方便、安全可靠的特点，受到了广泛的青睐。
随着工业技术的不断发展，气锁阀的原理和应用将会得到进一步的完善和拓展，为工业生产提供更加高效、安全的流体控制解决方案。

燃气安全切断阀执行标准的制定和遵守，对于保障燃气系统的安全运行和人员的生命财产安全至关重要。
各生产厂家和使用单位应当严格按照上述标准进行设计、生产、安装和使用，并定期进行检验和维护，确保燃气安全切断阀的正常运行和可靠性。
锁气阀的分类都有哪些呢？
锁气阀的分类都有哪些呢？在自动化控制系统中，锁气阀起到了重要的作用，它能够控制气体的行进方向，大小和速度，并且在气压不够时起到锁气作用，以防止系统中的设备过载。
锁气阀根据其不同的工作原理和结构可以分为以下几种：普通型锁气阀普通型锁气阀是功能简单，结构紧凑的一种锁气阀。
它主要通过锁气弹簧和气流触头的作用，使锁定机构的卡盘上锁死活塞，堵住气路的通道，达到锁气的目的。
在气压正常时，锁气阀处于开启状态，气体流经阀芯和卡盘，从而控制设备的行进方向、速度和大小。
而当气压不够时，气体无法克服卡盘的锁定力，从而锁死卡盘，实现锁气功能。
普通型锁气阀适用于一些基本的气控行业和简单的气压应用。
联动型锁气阀联动型锁气阀在普通型锁气阀的基础上增加了一个联动机构，使其具有更高的控制精度和更广泛的应用范围。
当气流触头被激活时，联动机构会带动控制气路的卡盘旋转，同时控制气路也随之发生改变，从而实现对气动元件的控制。
在气压不足时，联动机构可使其锁定状态解除，使所控制的设备有回路1的故障保护作用。
因此，联动型锁气阀在气压不足，气路故障发生时，能够达到快速安全切断气源的效果。
联动型锁气阀适用于中小型气动系统，如汽车、机器人、包装机械、制药机械等。
直动式锁气阀直动式锁气阀也叫电气式锁气阀，它是一种由电信号控制气流的高档锁气阀。
与普通型和联动型锁气阀不同，直动式锁气阀通过控制电磁铁抽取，使阀芯拔出，气流通畅，达到气路控制，当电磁铁失电后，阀芯受到弹簧复位，气流通道被完全堵死，达到锁气阀的效果。
直动式锁气阀有零时延，精确控制等优点，但是由于造价高昂，适用于一些精密气动控制系统和自动化生产线。
手动锁气阀手动锁气阀是一种通过手动旋转压杆以控制气流以达到气动元件的控制的锁气阀。
相比于其他三种锁气阀，手动锁气阀在结构和工作原理方面更为简单，易于操作，同时其材料成本低廉。
手动锁气阀多用于测试和调试气路系统及精度要求不高的小型气动控制系统。
总之，锁气阀的分类因其不同的工作原理和适用范围而不同。

AL系列气锁阀
在气动执行器上装一个气锁阀，无论何时当空气压力下降到低
于操作安全点时，它们将执行器与控制装置（定位器，电气分配器
等）隔离，保证执行器的特殊安全位置。
气锁装置主要由一个带设定值校正和大约20千帕差压的气动
压力开关所组成，操作一个或多个三通同步换向器( 取决于所需要
的功能 )。
当空气压力在设定值周围摆动时，差压避免了连续的不
合适的换向。
空气压力下降到设定值,开关装置立即动作，在空气压力逐渐下
降到设定值的情况下也是如此。
原理：
气锁装置压力开关对于操作设定可在20～93千帕
以内进行调节；要增加设定压力，你可以以顺时针方
向转动调整螺钉（1）。
当先导压力超过设定值时，活塞（8）抬起，克服
弹簧负载（5）。
相同的压力通过阀门（9）的中心孔，
并通过风道（23），它立即操作开关组合件。
此时，管
道U和S联通，而管道E关闭。
当先导压力下降到低于设定值时，由弹簧（5）推
动的活塞（8）使阀门（9）的中心孔关闭；通过向下
移动阀门（9），以前流过风道（23）的压缩空气放空
到大气。
开关组合件立即复位。
开关反向使管道U连
接到E并关闭S。
连接口由字母E－S－U标记。
备注:为了避免对执行器紧急动作时间的延迟，
压力开关应安装在靠近开关组处，并与小容量的管子
( 6 毫米)相连接。
